摘要:

在受灾环境中,快速评估损害、分析环境稳定性并将资源分配到可能存在受害者的最脆弱区域至关重要。这些任务由人类直接执行既困难又危险。利用地面机器人与空中机器人互补的能力,我们研究了一种空中与地面机器人协同作业的方法来解决这一问题。凭借更大的视场、更快的速度和紧凑的体型,空中机器人探索该区域并构建基于特征的3D地图图,同时向地面控制站提供实时视频流。空中机器人完成探索运行后,地面控制站处理地图并将其发送给地面机器人。地面机器人凭借其更长的运行时间、静态稳定性、载荷投送和远程会议能力,能够自主导航至已识别的高脆弱性位置。我们在一个包含障碍物和不平坦地面的室内建模环境中,使用四旋翼飞行器和六足机器人进行了实验。此外,我们还开发了一种低成本无人机附加模块,具备受害者检测等增值能力,可安装到现成无人机上。该系统在成本效益、能源效率和可扩展性方面进行了评估。

英文摘要:

In disaster-stricken environments, it's vital to assess the damage quickly, analyse the stability of the environment, and allocate resources to the most vulnerable areas where victims might be present. These missions are difficult and dangerous to be conducted directly by humans. Using the complementary capabilities of both the ground and aerial robots, we investigate a collaborative approach of aerial and ground robots to address this problem. With an increased field of view, faster speed, and compact size, the aerial robot explores the area and creates a 3D feature-based map graph of the environment while providing a live video stream to the ground control station. Once the aerial robot finishes the exploration run, the ground control station processes the map and sends it to the ground robot. The ground robot, with its higher operation time, static stability, payload delivery and tele-conference capabilities, can then autonomously navigate to identified high-vulnerability locations. We have conducted experiments using a quadcopter and a hexapod robot in an indoor modelled environment with obstacles and uneven ground. Additionally, we have developed a low-cost drone add-on with value-added capabilities, such as victim detection, that can be attached to an off-the-shelf drone. The system was assessed for cost-effectiveness, energy efficiency, and scalability.
